"The IOC has given athletes the right to blog at the Beijing Games this summer, a first for the Olympics. They're allowed, as long as they follow the many rules it set to protect copyright agreements, confidential information and security. The IOC said blogs by athletes 'should take the form of a diary or journal' and should not contain any interviews with other competitors at the games. They also should not write about other athletes. Still pictures are allowed as long as they do not show Olympic events. Athletes must obtain the consent of their competitors if they wish to photograph them. Also, athletes cannot use their blogs for commercial gain."
